Biography
Octavia was born in Nola, Roman Republic in 69 BC, the daughter of Gaius Octavius and Atia Balba Caesonia. Her first marriage was to 50 BC consul Gaius Claudius Marcellus Minor, who died in 40 BC after having three children with her. In 40 BC, her brother Octavian issued a Roman Senate decree that had her marry Mark Antony in order to avoid war between the two Roman leaders, but their marriage was loveless, and Octavia slept with her clothes on, feeling unappreciated. In 36 BC, Antony abandoned Octavia in favor of his Egyptian mistress, Queen Cleopatra, and they divorced in 32 BC. After the death of her son Marcellus in 23 BC, Octavia withdrew from public life, and she died in 11 BC.
